Question

So i did most of this, but the last bit has got me stuck.  I included the whole problem here.  Thanks for taking the time out to even read this.

A battery has a specified potential difference ?V between its terminals and establishes that potential difference between conductors attached to the terminals. A 17-V battery is connected between two parallel plates as shown in the figure. The separation between the plates isd = 0.37 cm, and we assume the electric field between the plates to be uniform. (This assumption is reasonable if the plate separation is small relative to the plate dimensions and we do not consider locations near the plate edges.) Find the magnitude of the electric field between the plates.

Find the magnitude of the electric field between the plates.
Conceptualize In a previous example, we illustrated the uniform electric field between parallel plates. The new feature to this problem is that the electric field is related to the new concept of electric potential.

Categorize The electric field is evaluated from a relationship between field and potential given in this section, so we categorize this example as a substitution problem. Use ?V = ?Ed to evaluate the magnitude of the electric field between the plates: E = |VB? VA| d = 17 V 0.37 ? 10?2 m = 4.59 E3 Use ?V = ?Ed to evaluate the magnitude of the electric field between the plates: E = |VB? VA| d = 17 V 0.37 ? 10?2 m = 4.59 E3 E = |VB? VA| d = 17 V 0.37 ? 10?2 m = 4.59 E3 E = |VB? VA| d = 17 V 0.37 ? 10?2 m = 4.59 E3 (a) Through what potential difference will it have passed after moving 1.74 cm?
97.4 V

(b) How fast will the electron be moving after it has traveled 1.74 cm??????????????????

Explanation / Answer

kinetic energy gained = potential gained*q

.5mv^2 = 97.4*q

electron mass = 9.12 x 10^-31 kg

q = electron charge 1.6 x 10^-19

so you can calculate velocity form this..

Hope this helps..
